1f pushed, it cannot deflect laterally. One, 'attains in this way amoving organ for the carbon which admits of actuating the latter from astationary part of the holder in both a forward and backward direction,even if the carbon be carried by a part,'which is movable relatively tothe stationary one,

e. g. a more or less inclinablepa-rt without the necessity, as forinstance with the use of in the annexed drawing a closed chain, ofguiding the chain as far as the burning end of the carbon and to providethere a guide-member for the chain,

e. a loose roller.

Fig. 1 shows a constructional-example of the invention 'in a sideelevation, partly in a section; Fig. 2

is a section alon the line 2-2. of Fig. 1.

The carbon-hol er shown consists of two parts a and o of which theformer is to be fixed on the casing of the arc lamp. Both parts arecoupled to each other b means of a oint a and a su port 6, variable initslength with the ai of a screw b.- At the upper end of the part a isfixed a cylindrical guide piece 0 for'a carbond,'which is vheld atits'rear end by a clam e, guided in .a groove-f of the part A providedwith a groove f, corresponding to he part a is I the groove f, and inthe grooves of both arts is guided a link chain 9 since the outerink-plates, lying on the side of the parts a p and a slide in-t-hegroovesand f. Some of the link-bolts are constructed 'as elongated bolts9, which .pass through the grooves f and f? and bear with a head (7against the backof the parts a and a. At its upper end this chain isconnected to the a v By means of a pair of clamp, a. At the bottom endof the chain 9 1s fixed a rack 9 en aging in a pinion h.

vel wheels 17, i this pinion is connected to a regulating motor by whichthe pinion may be rotated according to requirements in the one or theother direcpart of the holder a may be displaced and in each positionthe open chain 9 may be moved from its bottom end in'both a,for-" wardand backward direction; IClaim: I I I 1. A holder for the one of thecarbons of an arc lamp, comprising a carrier adapted to be fixed" onthe-casing of the arc lamp and provided with a groove, a sliding piecedisplaceably supported on this carrier,'c0

be fixed on. the casing of the arc lamp and provided with a groove, thecarrier consisting of two parts inclined at an angle relatively toeachother, a link connecting the two parts of the carrier to each other, acon- .trivance .for displacing the said angle, a sliding piecedisplaceably supported onthis carrier, means for "fixing a carbon onthis sliding piece, a chain fixed with its one endon'this sliding pieceand guided in the said 0- groove, a device for displacing the chain,andmea-ns connecting this device to the other end of the chain.
